(54) | Detecting cell-condition changes |
(57) Changes in the parameters or conditions of cells in a suspension are determined by
making impedance measurements of the suspension at a number of different frequencies,
these measurements being used to determine any change in the frequency-dependent impedance
characteristic, indicative of changes other than cell concentration or conductivity
of the medium in which the cells are suspended. |
